To all 'whom 'it may concern:

Be. it known that I, ;HENRY .C. KocH, a: States residing in Upper Yoder township,. in 'the count of Cambria and State of Pennsylvania, ha invented certain new and useful Improvemente in Furnaces; and I do hereby de'clare the following tobe a full, clear, and exact description of the invention, such' a's will en' able others skilled in the art to which it appe-tains to make and use the same. My invention relates gen'e'ally to the construction of firnaces and is especially adapted for use in connection with house heating furnaces, either hot air furnaces, hot water boiler fin-maces or steam boiler heating furnaces.. i

.My nvention consists or flue connection from the ash-pit of a furnace of the character described, to the! lower part of thesmoke flue of the same with a manually operated alve located in said plpe connection adapted to be-opened and closed as desired, whereby, when the ashes are Shaken down or poked from the furnace,

'said valve in the dust pipe connection-is opened, causing a draft t pass from the ashpit to the lower art of the smoke fine, therehy drawing od" the dust and ashes into the fine, together with escaping or sulfurous gases in such a way that neither the dust, gases nor heat therefrom will escape into frnace 'room or bother or dirty the operator;

i pit i'nto an intermediate or lower portionof By means ofmy invention any one is enabled to shake down the furnace without inhaling dust or gases. and his person and Clothes are kept' clean,` i i g In my arrangement the dust pipe leads prefrably from the upper part of the ash:

the smoke flu'e, which flue extends downwardly and in such a way aas to make a re ceptacle for dust and soot-which can be wthdrawn through a cleaning door at' the bottom of the smoke flue extension. The

lower part of theflue .ispreferably formed of bricks or other fireproof material and may Be made'larger than the upper part whch arries only the smoke and combus-i generallj ofa pipe said ue may be the same'size as'theupper' Patented ;aa 6; 1914.

tion ases, although the lower of the part', if desired.. I prefer, howe'ver, to make-g f the lower p a-t'larger, as it' gives more stor'- 'age capacty for dust` and scot and needs 'to' be cleaned There. is a sections hinged 'on at dian the hinge being made: tight and semi-crcilar etral line,

against closed, thereby preventing anyback draft' from the ash-pit to the' fluewhen the`valve is'closed; When it is desired to shake thefire anddrop the ashes in the 'ash-pit', the ,valve inthe dust pe is'opened by 'means'of a crankshaft to w ich isattached a lever,` the crank of said crank shaft being' connected to the-s'e'mi-cirout only' at :longerintervalsh tight seating 'flap valve in the dust pipe which fisi preferably made 'oi 'two -.60` the endssolderedor closed, and an abut'ment 4 rng is placed 'in the smoke pipe, ..which thevalve seats tightly when cular'flap valves as; indicated by 1inks.&'l`-he Operating. lever for the dist valve is pro vided with a 'convenient connection foropenin closed position.
